Template:Geobox Protected Area

The Blackdown Hills are a range of hills along the Somerset-Devon border in south-western England. It was designated an Area of Outstanding Natural Beauty (AONB) in 1991.[1]

The plateau is dominated by hard chert bands of Upper Greensand with some remnants of chalk, and is cut through by river valleys. The hills support an extensive range of wildlife leading to the designation of 16 Sites of Special Scientific Interest (SSSIs).

There is evidence of human occupation since the Iron Age. Fortifications include the remains of ancient hill forts, Norman motte-and-bailey castles and Second World War airfields. There are also religious buildings such as Dunkeswell Abbey and village churches. The hills are crossed by a network of minor roads with major transport routes including the M5 motorway running around the periphery.

Geography

Straddling the borders of Somerset and Devon, the Blackdown Hills AONB covers an area of 370 square kilometres (143 sq mi).[2] Heavily cut with sharp valleys, the hills reach their highest point of 315 metres (1,033 ft) above sea level at Staple Hill in Somerset. The hills in the southern part of the area, near Honiton in Devon, are more gentle. The Blackdown Hills are a sparsely populated area; much of the land is used for dairy farming.

The River Culm rises at a spring (grid reference ST2205016050) near Culmhead and flows west through Hemyock, then Culmstock to Uffculme before joining the River Exe on the north-western outskirts of Exeter. The name of the river is thought to mean 'knot' or 'tie', in reference to the river's twists and loops;[3] or is derived from a Celtic river-name meaning winding stream.[4] The River Otter rises near Otterford, where a stream feeds the Otterhead lakes: (ST225152). It then flows south for32 kilometres (20 mi) through East Devon to the English Channel at the western end of Lyme Bay. The Permian and Triassic sandstone aquifer in the Otter Valley is one of Devon's largest groundwater sources, supplying drinking water to Taunton.[5] The other rivers are the River Yarty and the Corry Brook.

Villages in the northern, Somerset part of the hills include Staple Fitzpaine, Buckland St Mary, Whitestaunton, Wambrook and Churchstanton. The larger, more southerly area in Devon includes Dunkeswell, Upottery, Smeatharpe, Hemyock, Blackborough, Yarcombe, Membury, Stockland, Sheldon and Cotleigh.

Geology

The geology of the Blackdown Hills together with the adjoining East Devon AONB is unique in south-west England,[6][7] forming part of the only extensive outcrop of Upper Greensand in the region.[8]

The Blackdown Hills form a flat plateau dominated by hard chert bands, made up of clay with flints, of Upper Greensand with some remnants of chalk.[9] The cretaceous rocks rest over eroded Jurassic and Triassic beds, with an outcrop of Rhaetian beds.[10] In the western areas the Upper Greensand is devoid of calcareous material but the sands yield fossils of marine bivalves and gastropods (snails) preserved in silica.[11]

Climate

Along with the rest of south west England, the Blackdown Hills have a temperate climate that is generally wetter and milder than the rest of England. The mean temperature is approximately 10 °C (50 °F) and shows a seasonal and a diurnal variation, but because of the modifying effect of the sea the range is less than in most other parts of the United Kingdom (UK).[12] January is the coldest month with mean minimum temperatures between 1 °C (34 °F) and 2 °C (36 °F). July and August are the warmest months, with mean daily maxima around 21 °C (70 °F).[12] December is normally the most cloudy month and June the sunniest.[13] High pressure over the Azores often brings clear skies to south-west England, particularly in summer.

Cloud often forms inland, especially near hills, and acts to reduce sunshine. The average annual sunshine totals around 1,600 hours.[13] Rainfall tends to be associated with Atlantic depressions or with convection. In summer, convection caused by solar surface heating sometimes forms shower clouds, and a large proportion of rain falls from showers and thunderstorms at this time of year. Average rainfall is around 31 to 35 inch (800 to 900 mm).[14] About 8 to 15 days of snowfall is typical.[15] From November to March, mean wind speeds are highest; winds are lightest from June to August. The predominant wind direction is from the south-west.[16]

Ecology

There are 16 Sites of Special Scientific Interest (SSSIs) in the Blackdown Hills ranging from the 156-hectare (390-acre) Black Down and Sampford Commons to Reed Farm pit at just less than 1 hectare.[7] In total they cover 640 hectares (1,600 acres), or just under 2% of the AONB. Of these SSSIs 79% are deemed by English Nature to be being positively managed.[7] SSSI is a conservation designation denoting a protected area in the United Kingdom, selected by Natural England, for areas with particular landscape and ecological characteristics. It provides some protection from development, from other damage, and (since 2000) also from neglect, under the Countryside and Rights of Way Act 2000.

The grasslands, heathland, meadows and mire support extensive populations of birds such as Barn owls (Tyto alba) and nightjar, with butterflies including Marbled White (Melanargia galathea), Green Hairstreak (Callophrys rubi) and the Gatekeeper Butterfly (Pyronia tithonus). The flora includes the Heath Spotted-orchid (Dactylorhiza maculata), Corky fruited water dropwort (pimpinelloides), Green-winged Orchid (Anacamptis morio), Heather (Calluna vulgaris), Lousewort (Pedicularis) and Birds foot trefoil (Lotus corniculatus). The hedgerows and woodlands are made up of Ash, Hazel (Corylus), Grey willow (Salix cinerea) and Pedunculate Oak (Quercus robur) which support populations of Dormouse (Gliridae), Common Lizards, Siskin, Stinking iris (Iris foetidissima) and the Purple Hairstreak butterfly (Neozephyrus quercus). The rivers and streams are home to Kingfisher, Otter and the Daubenton's bat.[17]

Blackdown and Sampford Commons have extensive surviving examples of the heathland, carr woodland and marshy grassland habitats that have developed on the acidic soils overlying the Greensand and Keuper Marls of the Blackdown Hills. The heathland supports a typical invertebrate fauna, including a wide variety of butterfly species, and with spiders notably abundant. The site is regionally important for birds which favour heathland habitats.[18]

Quants, a grassland clearing in a forestry plantation well-known for its butterflies including Duke of Burgundy, Marsh Fritillary and Wood White,[19] is a candidate for Special Area of Conservation (cSAC). These are designated under the European Commission Habitats Directive (92/43/EEC) as internationally important habitats.

History

Palaeoenvironmental studies have shown that organic material began to accumulate on the Blackdown Hills in the Mesolithic and Neolithic periods with areas of open meadow, grass land with small woodland components being identified.[20]

Notable archaeological sites include the Iron Age hill forts at Membury Castle, Hembury and Castle Neroche. Hembury is a Neolithic causewayed enclosure near Honiton. It dates to the late fifth and early fourth millennia BC and is believed to have been the capital of the Dumnonii tribe. The fort is situated on a promontory to the North of and overlooking the River Dart at approx 178 m (584 ft) above sea level.[21] It has given its name to some of the earliest Neolithic pottery in southern Britain. An Iron Age hill fort[22] was later built on the same site. There has been archaeological evidence found on the site of Roman Military occupation, suggesting a Fort within the existing Iron Age site. It is now a Scheduled Ancient Monument.

Fourteen hill slope enclosures, dating from the Iron Age have been identified on the Blackdown Hills, [23] and prehistoric remains, from about 100 BC, have been found in Hemyock.

Earthworks at Castle Neroche

Castle Neroche is a Norman motte-and-bailey castle on the site of an earlier hill fort near Staple Fitzpaine. The hill rises to 260 metres (853 ft) on the northern escarpment of the Blackdown Hills. The castle was probably built by Robert of Mortain in the 11th century and probably went out of use in the 12th.[24] Around the crossroads at Staple Fitzpaine there are several large sandstone boulders. They are called devilstones and are said to have been thrown by the Devil from Castle Neroche. According to legend if you prick them with a pin they draw blood. English word 'Stapol' means pillar or post and it is thought likely that this gave the village the first part of its name.[25] The second part of the name comes from the Fitzpaine family who owned the manor between 1233 and 1393.[26]

A Roman bath house and Edwardian folly in the village of Whitestaunton were excavated by the television series Time Team.[27] There is also evidence of iron workings in the Romano-British period, at Dunkeswell, which Radio-carbon dating has placed in the 2nd century. [28] It has been suggested that these and other iron based technologies gave the hills a fairly industrial landscape during the Romano-British period, providing a source of the name Blackdown Hills.[29] Local iron ores were smelted at Hemyock in small bloomeries (furnaces) to produce pure iron until the Middle Ages.[30]

At Simonsburrow a battle between the native Britons and King Ine's Saxon army, put an end (temporarily) to the Kings expansion to the west. In 710, Ine and Nothhelm fought against Geraint of Dumnonia, according to the Anglo-Saxon Chronicle;[31] John of Worcester states that Geraint was killed in this battle.[32] Ine's advance brought him control of what is now Devon, the new border with Dumnonia being the river Tamar.[33]

Just to the north of Culmstock at Culmstock Beacon, is one of a chain of Elizabethan beacons built to warn of possible invasion by the Spanish Armada.[34] On 5 November 1380, King Richard II granted Sir William and Lady Margaret Asthorpe a licence to crenellate the Hemyock manor house; meaning the permission to fortify it.[35] Over the centuries, Hemyock Castle had many notable owners including Lord Chief Justice Sir John Popham. During the English Civil War it was held for Parliament, subjected to a brief but brutal siege and eventually slighted to destroy its military value. Parts of the castle walls, towers and moat still remain. They are a scheduled ancient monument and include displays of history and archaeology. The castle was also owned by General Sir John Graves Simcoe the first lieutenant-governor of Upper Canada in 1792.[36] He is buried at Wolford Chapel near Dunkeswell. The chapel is now owned by the Province of Ontario.[37]

Wellington Monument

Cold Harbour Mill was built around 1800 to exploit the available water power of the River Culm and was used for wool and yarn production until its commercial closure in 1981. It is now managed by an educational trust and plays a role in telling the industrial history of the area.[38]

The Wellington Monument is located on Wellington Hill at grid reference ST137171, 3 km (1.9 mi) south of Wellington, Somerset. It was erected to celebrate the Duke of Wellington's victory at the Battle of Waterloo. The foundation stone was laid in 1817, on land belonging to the Duke, but the monument was not completed until 1854. Its design was inspired by an Egyptian obelisk, but in the shape of the type of bayonet used by Wellington's armies.[39] It is now owned by the National Trust, and is floodlit at night. The viewing platform is currently (2007) closed due to safety concerns.[40]

Mare and Foal, 1917, by Robert Bevan

The artist Robert Polhill Bevan worked in the Blackdown Hills from 1912–1925 as a guest of landowner and amateur artist Harold Harrison. Until the end of his life Bevan continued to paint in the Bolham valley and nearby Luppitt his angular style sitting well with the strong patterning of the landscape.[41] Many of the images that he produced in the area are now in national museums.

In the Second World War, airbases were built at Dunkeswell, Upottery and Culmhead.[42] Dunkeswell Aerodrome (IATA: N/A, ICAO: EGTU) was built in the Second World War by the RAF, briefly used by the USAF, and then the Fleet Airwing 7 of the USN;[42] and is now a busy civilian airfield with a mix of light aircraft, microlights and parachuting. It was the only American Navy air base commissioned on UK soil during the Second World War.

Government and politics

The Blackdown Hills have, since 1991, been designated as an Area of Outstanding Natural Beauty (AONB).[1] As they have the same landscape quality, AONBs may be compared to the national parks of England and Wales. AONBs are created under the same legislation as the national parks: the National Parks and Access to the Countryside Act 1949. However, National Parks, unlike AONBs, have their own authorities and have special legal powers to prevent unsympathetic development. By contrast, there are very limited statutory duties imposed on local authorities within an AONB. Further regulation and protection of AONBs was added by the Countryside and Rights of Way Act 2000.

The total population of the Blackdown Hills AONB in 2001 was 13,300; of which 10,500 live in Devon and 2,800 within Somerset.[7] Many of the villages have their own parish councils which have some responsibility for local issues. The Blackdown Hills AONB is managed by a partnership of public bodies, local organisations and voluntary groups with an active interest in the Hills. Funding is provided by Devon and Somerset County Councils, East Devon, Mid Devon, South Somerset and Taunton Deane Councils and Natural England.

The AONB straddles the borders of three parliamentary constituencies: Tiverton and Honiton, Taunton and Yeovil. The area is also part of the European Parliament's South West England constituency.

Religious sites

The Church of St Peter in Staple Fitzpaine

Dunkeswell Abbey, a Cistercian monastery and offshoot of Forde Abbey, was founded in 1201 by William de Briwere. The abbey was closed in 1539 and granted to Lord Russell. It was mostly demolished promptly, though a section remained in domestic use until the 19th century. In 1842, a parish church was built on a part of the site. Some surviving fragments of monastery include the partial end wall of the cellerars range and parts of a gatehouse. Some carved fragments survive within the Victorian era church.[43]

The Church of St Peter in Staple Fitzpaine was originally build in the Norman style, and has a Norman doorway reset in the south aisle. The chancel dates from the 14th century; the north aisle was added and the church refenestrated in the 15th century. The tower dates from about 1500. The south porch and the vestry are much more recent, dating from 1841. The crenellated 3-stage tower, has merlons pierced with trefoil headed arches set on a quatrefoil pierced parapet. The church has been designated by English Heritage as a grade I listed building.[44]

Transport

The Blackdown Hills are crossed by a network of minor roads. There are several major roads including the A30, A303 and A35. The M5 motorway is at the northwestern boundary of the AONB. The Reading to Plymouth railway line and the remains of the Grand Western Canal run, quite close in places, to the west of the M5 motorway but do not pass through the Blackdown Hills.

The Culm Valley Light Railway opened in 1876, having been built by local enterprise. The line was purchased by the Great Western Railway, which had operated it from the start, in 1880. The line closed to passengers in 1963 but served the milk depot at Hemyock until its closure in 1975.[45]
